Can we agree Nintendo should go third party, now?

Indeed. 

Furthermore, with Sega, they had a long string of failures that led to their demise as a hardware manufacturer. The Genesis/Mega Drive was really the exception rather than the rule. The Master System didn’t do well at all as it was dwarfed by the NES. The Saturn flopped, all their handhelds flopped. The Dreamcast had a promising start, but as soon as the PS2 was announced, that was all she wrote.

With Nintendo, aside from the Wii U and GameCube, all of their consoles and handhelds have ranged from so-so (N64/3DS) to absolutely juggernaut (DS/Wii/Switch).
